1. Oil that has a density of 880 kg/m flows under a head of 30 m. The pipe that the oil flows through is 3000 m long and 0.35 m in diameter. Due to the cooling along the span of the pipe the viscosity changes, this may be taken as 0.57 kg/m-s over the first 1500 m and 1.14 kg/m-s over the second 1500 m. Confirm that laminar flow conditions exist and calculate the flow in dm/s. Neglect entry and exit losses. Answer 37.185 dm/s

31 Yuri wants to determine the permeability of an aquifer. The aquifer has a test well 300-mm in diameter with two observation wells. A pumping test was conducted for 24 hours with the discharge being held constant at 5,721.4 m^3/day. The first one, 81.07 meters from the test well, has a draw-down of 0.6 meters. The second one, 40 meters from the test well, has a draw-down of 1.43 meters.The static water table penetrates the well to a depth of 25 meters. Determine the radius of influence of the aquifer in meters. Round off to three decimal places.
